Power Failure During Dialysis; Manually Operating The Blood Pump; Returning The Blood To The Patient Manually - Fresenius Medical Care 2008T Operator's Manual

Power Failure during Dialysis

In case of a power failure, the blood pump stops and the venous line clamp closes. The
dialysate flow pump, heater, blood leak detector, and level detector are non-functional. All
function lights go out. A steady, audible alarm will immediately sound for seven minutes that
cannot be silenced with the Mute key. It can be silenced manually, however, by removing
the 9-volt battery from the back of the machine.

Manually Operating the Blood Pump

In the event of a power failure during treatment, the 2008T blood pump can be manually
operated to return the blood to the patient or to keep the blood in recirculation if a quick
resumption of power is anticipated. Either option is accomplished with the auxiliary hand
crank supplied with the machine (see Figure 57). The hand crank is attached to the back of
the machine.

Note: As a precaution, the handle will detach from the crank when attempting to turn the
rotor in the wrong direction. An arrow embossed on the face of the pump-segment housing
points in the correct direction of rotation (clockwise).

Returning the Blood to the Patient Manually

To return the blood manually:
1. Remove the bloodline from venous line clamp. If you are performing single-needle
dialysis, remove the pump segment from the single-needle pump.
2. Replace saline bag with a fresh bag if necessary.
3. Using a hemostat, clamp the arterial bloodline directly above the saline "T".
4. Open the saline line clamps and rinse the blood in the tubing below the saline "T" back to
the patient. When the blood in the line has been rinsed back to the patient, close the
saline line clamps.
5. Clamp the arterial bloodline directly under the saline "T". Remove the clamp on the
bloodline above the saline "T" and open the saline line clamps.
6. Open the pump door and flip the rotor latch outward (see Figure 58 #1).
